This Think Paper addresses the theme of Public-Private Partnerships (PPP) and raises questions about the validity of these partnerships for public administrations, the private sector and citizens. When the requirements of these parties are well served, then we can expect PPP to become an accelerator for the investments in the cultural heritage sector. This Think Paper provides an overview of what PPP is, with a special focus on PPP and cultural heritage, discussing opportunities and advantages, identifying some challenges, and proposing a set of future steps to gain more benefits from PPP.
